BACKGROUND OF THE PRESENT INVENTION

1. Field of Invention

The present invention relates to a dust collector, and moreparticularly, to a water filtered dust collector.

2. Description of Related Arts

An ordinary dust collector has a dust chamber or is equipped with anextra dust bag based on the dust chamber. As each type of dust collectorhas a different model, many factors such as the shape and the operationmethod of each dust collector should be considered when manufacturingthe corresponding dust chamber. Also, in general, the dust chamber canbe used only once, or it should be cleaned after being used for severaltimes. But after being used for a too long time, more and more dust hardto be cleaned will accumulate. And therefore, the reusability of thedust chamber is affected, the use-cost of the product is increased andit is not environmentally friendly. And for the dust collector with adust bag, the material of the dust bag may generally allow both air anddust pass through. The dust collector is used to clean the dust in theroom, but the dust will suspend in the air through the dust bag of thedust collector. Also, the material of such a dust bag is generally soft,and therefore, some special material is needed to connect and fix withthe dust inlet port of the dust collector, which is inconvenient for theusers replacing the dust bag. Furthermore, such dust bag can be usedonly once, so it's not environmentally friendly.

DETAILED DESCRIPTION OF THE INVENTION

The present invention is further described with referent to theaccompanying drawings as follows.

As shown in FIGS. 1 to 4, the water filtered dust collector comprises ahousing 1 with a handle that is consisted of front and back housings12,14, which are engaged with each other. A battery package 2 isdisposed at one end of the housing, and a suction nozzle 3 is disposedat the other end. A suction nozzle mounting 32 communicating with thesuction nozzle is disposed at the bottom of the suction nozzle. Asuction nozzle fixing bush 4 is disposed between the suction nozzlemounting and the housing to connect and fix them. An electric motor 5driven by the batteries in the battery package and fan blades 6 drivenby the electric motor are disposed in the suction nozzle fixing bush andthe housing. A water vessel 7 for holding water is disposed in parallelto the suction nozzle on the suction nozzle mounting. An air steeringpipe 42, which can redirect the water-filtered air, is disposed at aposition corresponding to the suction nozzle on an end surface far fromthe suction nozzle of the suction nozzle mounting. An air inlet pipe 44is disposed on the septum of the suction nozzle fixing bush, with oneend inserted into the water vessel to communicate the suction nozzlefixing bush with the water vessel. The air steering pipe 42 extends in adirection opposite to the direction the air inlet pipe 44 extends in thesuction nozzle fixing bush 4 to form a cavity 46, which corresponds tothe center of the fan blades 6. The air inlet pipe 44 is a straight pipewith an elbow 48 of 90 degrees at the end of the water vessel 7. Thewater vessel 7 connects with the suction nozzle mounting 32, and a boss322 is disposed on the suction nozzle mounting, on which the watervessel can be enclosed removably. The air inlet pipe 44 extends throughthe suction nozzle mounting and is located at the center of the watervessel, and the connection between the suction nozzle mounting and theair inlet pipe is a tight connection. The battery package 2 and thehousing 1 are fixed and connected by a connection plug 8. The connectionplug 8 has a body 82, with two elastic clip pins 84 at one end of thebody, wherein the width of the two ends of the body is greater than thatof the clip pins, and the two ends are disposed within the clip socket16 at a corresponding position of the housing 1. A handheld handle 18 isformed after engaging the front and back housings 12,14. And an exhaustslot 9, which may exhaust the air from the air steering pipe 42 out ofthe dust collector, is disposed at the position opposite to the handle.The water vessel 7 may be cylindrical. Screws 10 are used to fix them inmany places when assembling the front and back housings.

When assembling, fill the water vessel 7 with water at first, with thesucker downwards, and the water surface in the water vessel lower thanthe opening of the air inlet pipe. Then enclose it on the boss 322 onthe suction nozzle mounting 32 of the dust collector. Thus a layer ofspecial water-solidifiable glue is disposed previously between them suchthat an airproof effect may be achieved after they are connected. Whenbeing used, a control switch 9 is turned on first to communicate theelectric motor 5 with the batteries in the battery package 2, such thatdriven by the electric motor, the fan blades 6 begin rotating and asuction is generated, drawing out all the air in the suction nozzlefixing bush 4, the suction nozzle mounting 32 and the dust collector toform a vacuum state. Thus a strong suction is generated at the sucker 34of the suction nozzle 3. And therefore, when the sucker contacts theobject surface to be cleaned, the dust is sucked in by the strongsuction via the sucker, moves towards the suction nozzle mounting 32along the suction nozzle, and then enters the water vessel 7 filled withwater along the air inlet pipe 44. Because an air inlet pipe with anelbow 48 of 90 degrees is disposed at the end of the air inlet pipe 44,water in the water vessel will not flow back into the suction nozzlefixing bush. After entering the water pipe, the air with dust contactsthe water surface, and will suspend in the water, instead of adhering tothe pipe wall after being filtered by water. So the air is without dustwhen entering the air steering pipe 42. Subsequently the clean air isexhausted out of the dust collector via the exhaust slot 9. Finally thewater vessel can be disassembled to replace the water, and then enclosedon the suction nozzle mounting for reuse.

As described above, compared with prior art, the water filtered dustcollector has the following advantages: easy for cleaning, as it isfiltered by water; easy for replacing, as it is convenient to assembleand disassemble the device collecting dust; environmentally friendly, asthe water vessel used for collecting dust and filtering can be reused;and reducing the use-cost, as the water vessel can be made into variousshapes and thus has a high applicability.
